The frame or bracket 2 is provided upon rgasms chaser wans 'tipefieiag arm es),

ii lfich arm is adapted to be fixedly secured to the inner face of one of the side-rails of the boat 1. This bracket 25 is provided with an extending arm ,isprovidecl =with arounded endpiece 21 so is journaled a foot-treadle 27 Thisfoot 26 upon which arm treadle 27 is provided with a downwardlyextending arm 28 having a foot-engaging.

member 29 extending laterally therefrom. A connecting hook 30 is secured'to the upper end of the foot-treadle 27, as illustrated in Figs. 1 and 3, and this connecting hook 30 is provided with a downwardlyturned end 31, which downwardly-turned end 31 fits over thegrooved-portion 32 of the handle 14 of the oar.

It should be understood that the band 17 may be normally held in the position shown 'n Fig. 1, but if it should be desired to decrease the distance at which. the paddle 16 may dip into the water, the band 17 may be swung to the position shown in Fig. 8, in dotted lines. As the handle 14 is drawn rearwardly the paddle 16 will also be drawn rearwardly and in this manner the operator of the oar may face the bow of the boat and be enabled to efliciently steer the same. It should be understood that the oar-carrying casing may be readily tilted upon the journal pins 6, but this casing is not journaled so as to allow the same to have any lateral swinging movement, as all of the lateral swinging movement will be supplied through the medium of the cooperation of the handle 1 1 and the paddle 16.

In order to assist in operating the paddle 16 a foot-treadle 27 has been employed, the structure of which has been previously described. By operating the foot-treadle 27 it will be seen that the loop-portion 31 will engage the handle 14 of the oar and assist in oscillating the same, by the oscillation of the foot-treadle 27.

It should be further borne in mind that, owing to the fact a foot-treadle has been attached to the handle, the operator may apply a greater amount ate the oar, owing to .the fact that he may not only apply his manual strength thereto, but he may also apply his entire weight, by forcing his weight directly upon the foottreadle, and at the same time pulling upon the handle 14.

It should be further understood that by means of the foot-treadle 29 the oar will be greatly assisted in returning the same to its original position, ready for the next stroke.

The gear 12 is provided with a socket portion 32 for receiving the operating handle 14, as illustrated in Figs. 1 and 3. The gear 15 is provided with a socket portion 15 for receiving the blade 16 of the oar.

By carefully considering Fig. 6 it will be of strength to operseen that the loop 30 is provided with a laterally-extending pin 30, which pin works in a transversely-extending slot 31 carried by the treadle 27. It will be seen that the pin 30 may have a slight lateral swing in the slot 31 to allow for the swing of the handle 14 while operating the paddle 16.

What is claimed is:

l. A device of the class described, comprising a support, a casing carried thereby, a foot-treadle, said foot-treadle provided with a connecting link having a looped upper end, an operating handle, said loop extending around said operating handle and said foot treadle adapted to facilitate the operation of said operating handle.

2. A device of the class described comprising a support, a casing carried thereby, an oar operating mechanism placed within said casing, a stop band extending over said casing, and means for holding said stop band in a set position for limiting the vertical swing of said casing upon said support.

3. A device of the class described comprising a support, said support comprising a plurality ofupwardly extending arms, a casing pivotally mounted between said arms, an oar actuating mechanism placed within said casing, a stop band pivotally secured to the upper ends of said'arms, and an adjusting screw carried by one end of said band and engaging one of said arms for holding said stop band in a set position for limiting the upward swing of said casing 'upon said arms. v p

4. A device of the class described comprising a support, said support comprising a plurality of upwardly extending arms, a casing pivotally mounted between said arms, an oar actuating mechanism carried by said casing, astop band provided with annularly bent ends pivotally secured to the upper ends of said arms, a thumb screw passing through one end of said band, a clamping block carried by the lower end of said thumbv screw, and said clamping block adapted to engage the upper end of one of said arms for firmly holding said stop band in a set position for limiting the upward swing of said casing upon said arms.
